I loved reading this. You have managed to turn what I think is a cliché and overused subject (love, heartbreak, you know how it goes) into something fresh and inviting. In fact, it reminded me a lot of *estallidos' short prose; conversations between lovers that we are privileged to overhear. The piece itself felt private and exciting to me, but at the same time evoked a quiet loneliness.
I feel the desperation in the woman's voice - the repetition of I didn't mention is almost excruciating by the ninth stanza - and the coolness of her lover, the way he brushes off her thoughts with 'damp' laughter. I felt I could relate to this as I thought back to how long it took my own partner to say those three words. Perhaps it will be worth the wait and the madness for her, too.
I felt the flow was spot-on. I didn't feel myself stuttering or lost for pause at any point, and the line breaks felt natural and well-placed to me. The singling out of madness could be attractive... was perfect and the emphasis of that line tied together the emotional imagery for me. It doesn't feel at all too dramatic. As for the mentions of Ra and Aphrodite, I liked it. It ties into the title like you say, and the end line as she envisions the blueprints was wonderful. They say a poem is made by its final line and yours left a beautifully sour taste in my mouth. Bravo.
